Hello,
The Apple Pencil Pro brought with it the UICanvasFeedbackGenerator API, which lets us trigger haptic feedback on discrete events initiated by the pencil. That works fine.
My question then: is it possible / are we "allowed" to trigger haptic feedback on events that weren't initiated by the pencil?
For example, say the user is using a left hand finger to drag a slider, while holding the pencil in their right hand-- would it be possible to make the pencil vibrate to indicate the dragged slider knob reached a certain point?
Or is the rule that vibration is only possible/allowed when the pencil itself generated a touch?
Thanks!
